This instructable not only gives the reader the information needed to create a clap-clap on/clap clap off switching circuit, but the logic used to make a hardware-only clap-on, clap off circuit. More information on a hardware-only version can be found in the final section of this instructable.

This circuit employs some very simple and cheap circuitry, and a simple program. It is relatively easy to make a hardware only clap on/off circuit, but I wanted to create a circuit that required two claps to switch on, and two claps to switch off. Th ....etc

CLAP SWITCH


Here s a clap switch free from false
triggering. To turn on/off any ap
pliance, you just have to clap
twice. The cir-cuit changes its output state
only when you clap twice within the set
time period. Here, you ve to clap within 3
seconds.
The clap sound sensed by condenser
microphone is amplified by transistor T1.
The amplified signal provides negative pulse
to pin 2 of IC1 and IC2, triggering both the
ICs. IC1, commonly used as a timer, is
wired here as a monost ....etc

HELLO,
this is prashant,btech ece(2nd year). I hv 2 submit a project& the project name is clap switch. i have a problem for makin report & how i would make on pcb 2 get neat &clean diagram. i hv ckt diagram also& i hv done on bread board. in the ckt 3 transistor,2 led &capacitor, resistor used.when i go for pcb it look sm complicate. so can u plz help me 2 get simple diagram on pcb.

clap operated fan speed control

Here is the circuit of clap-operated remote control fans is used to control not only switching properties but also control speed of fan. The main advantage of clap operated remote control for fan is, it can control up to ten-step speeds of fan where normally a fan has three to five step speeds.
Circuit description clap operated remote control for fan
This entire circuit clap operated remote control for fan is divided into four major section i.e. sound-operated trigger pulse generator, clock pulse generator, cloc ....etc

Clap Switch
Sound operated switch using a simple transistor circuit
The operation is simple. Clap and the lamp turns on. Clap again and it turns off.
The electret microphone picks up the sound of your claps, coughs, and the sound of that book knocked off the table. It produces a small electrical signal which is amplified by the succeeding transistor stage. Two transistors cross connected as a bistable multivibrator change state at each signal. One of these transistors drives a heavier transistor which controls a lamp.
